Posters Posters Posters! (plus a prize drawing!)

I am working on my next book from Stenhouse, a counting titled How Many? I took a little time away from that this summer to work on a set of shapes posters. I designed them, Tracy helped me refine them, and the Stenhouse production team made them beautiful.

Poster images

Most of the shapes posters available to teachers are very very bad. (Seriously…go ahead and do a quick image search on shapes posters….I’ll wait.) Everything is in standard orientation; the triangles are mostly equilateral; the rectangles never are, and on and on.

The Which One Doesn’t Belong? shapes posters are mathematically correct, and they also give everyone in the room something to think about. Why is there a square on the rectangle poster? Is a heart a shape? What about a spiral? Does a curve have to be curvy? Does biggest count as a property? These are the kinds of questions I meant these posters to elicit, while still serving the noble purpose of being a visual reference for important geometry vocabulary.

I am very excited to see these posters out in the world. If you’ll help me spread the word that they exist (and where to find them), I’ll do two things: (1) Express my heartfelt gratitude, and (2) Put your name in a drawing for one of two classroom math play sets.

There are three ways to enter:

  1. Tweet a photograph of these posters in the wild to the #wodbposters hashtag.
  2. Design your own Which One Doesn’t Belong? poster and tweet a photo of it to the #wodbposters hashtag.
  3. Send me a note through the About/Contact page on this blog right here, and include this set of characters: #wodbposters . (This is essential as I’ll search my inbox for it when assembling the drawing.)

Here are the rules:

  • One entry per person
  • You may tweet as many times as you like on the hashtag (In fact, please do!), but together those will count as a single entry. #unitchat
  • You may have someone else tweet or write on your behalf. This is totally fair.
  • Entries end at 11:59 p.m. Central Time on November 1.
  • The drawing takes place using a spreadsheet and random.org on November
  • Winners will be notified by whatever means they entered (I’ll tweet you if you tweeted; email if you submitted through the contact page), and we’ll connect at that time to work out a shipping address.
  • Worldwide participation is welcome.
  • A classroom math play pack includes Tiling Turtles, Spiraling Pentagons, Curvy Truchet Tiles, 21st Century Pattern Blocks, and maybe something else, depending what prototypes I’m playing around with when I put the packs together.
  • If you have already tweeted a photo of the posters in the world, you probably didn’t use the #wodbposters hashtag, which is how I’ll search for them when the drawing comes to an end, so you’ll need to do that if you want to be entered.
